The resistance of the pTC thermistor is measured at ambient temperature that is sufficiently low to avoid self-heating. The temperature at which the resistance of the PTC thermistor begins to increase rapidly is called "Curie," (Te), which is defined as the temperature at which the resistance value is twice the minimum resistance value (Rmin). The resistance/temperature relationship is shown in the specific thermistor of Figure 1, and the temperature coefficient α between any two temperatures (Τι, τ2) is given by the following equation (丨): 1 R2 〇gF" cc = 2.303—^ 100 %/°C........................(1) T2,T丨When the voltage applied to the PTC thermistor increases, The temperature of the PTC thermistor will rise slowly due to self-heating.

Description of invention (2) Heat, Gradually increase. When the temperature reaches the Curie temperature (Te), it shows a negative negative current characteristic, that is, when the voltage continues to increase, the current will decrease. This is more detailed in Figure 3, which shows the heat through PTC. The relationship between current and time. As can be seen in Figure 3, when a voltage is applied to the PTC thermistor, the current will decay. Initially, a very large current will flow through the PTC thermistor. When the time for applying this electrical waste increases, the current will suddenly decrease until it reaches a low level of 4, where it will remain fairly constant. This low level is sufficiently lower than the normal operating current of a heat generating resistor, and thus long term The use of a PTC thermistor to generate heat has advantages over resistors. However, the characteristics clearly shown in Figure 3 prevent the use of PTC thermistors as heating elements in electrical appliances having heating members, especially That: Some appliances that contain batteries (rechargeable or other types) for operating the heating member. As described above, when a voltage is applied to the PTC thermistor, a large current is drawn from the power source to start the PTC. heat In the case where the power supply is a battery, when the battery is not designed to provide this large current, the normal life of the battery will be significantly shortened whenever the electric appliance is activated. Even if the current is reduced over time to A low level, which still cannot be properly remedy. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide an electrical appliance having a PTC heating member, and a method of operating the same, wherein the aforementioned disadvantages are alleviated Or at least provide the public with a useful alternative.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT • Referring to Figure 4, there is shown a circuit diagram of an electrical appliance, such as an electric hair curler, generally designated 100 in accordance with a first embodiment of the present invention. The electrical appliance 100 includes a positive temperature coefficient (PTC) heater 102 electrically coupled to one or more batteries 106 via a switchable on/off switch 丨04, and an electrical source receptacle 108. The battery 1 〇 6 can be, for example, a disposable battery such as a dry battery, or a brake battery. The power outlet 108 is electrically connected to a receiver 〇1〇, which is δ etched and connected via a transformer to a commercially available ac source, such as 22 〇v, or an external power source for the battery. A power plug 丨 12 is connected.

Description of the invention (5) A power supply with a higher power supply than the battery 1 〇6. When the power plug 112 is connected to the power outlet, power is supplied from the external power source to the pTC heater. Simultaneously, one of the power contact sockets 108 is movable by the movable contact arm 114 without being in contact with a static contact arm 16 whereby the power supply from the battery 106 is disconnected. The electrical appliance 10 is then activated and the PTC heater 1〇2 is heated under the power supplied by the external power source. The user can manually remove the power plug 112' from the power outlet 1'8 to disconnect the electrical appliance from the external power source when desired. The movable contact arm is removed from the power outlet 1〇8 to remove the power plug 112. 114, under the biasing force of the spring, returns to its normal state, contacts and electrically connects the static contact arm 116 such that the PTC heater 102 is now energized, and thus the battery is heated or insulated by replacing the external power source. . With this configuration, the extremely large initial power for starting the PTC heater 102 is generated by an external power source, and is not generated by the battery 1〇6 in the appliance 1〇〇. The on/off switch 104 is operable to connect or disconnect electrical connections between the PTC heater 102 and the battery 106 and/or the power outlet 108 whereby the PTC heater 102 is coupled to an external power source. Figure 5 shows a circuit diagram of an electrical appliance, generally designated 200, in accordance with a second embodiment of the present invention. In the electrical appliance 200, when the power socket 208 is connected to the power plug 212, a movable contact arm 214 is moved to contact and electrically connect a static contact arm 216 such that if the power plug 212 is connected to the power plug 212 via a transformer, When an external power source is passed, the electrical appliance will be activated due to the passage of electricity, and the PTC heater 202 will be heated. At the same time one or more rechargeable batteries 206 are controlled by a charger integrated circuit (IC) 220.

Invention description (6), will be The external power supply is charged to recharge. The rechargeable battery 206 is also manufactured and sold by Raychem Circuit Protection, a division of Tyco Electronics, and is protected by a resettable device 222 under the trade name PolySwitch. This device is a polymeric PTC nonlinear thermist that limits the amount of current that can pass therethrough. At this time, even when the PTC heater 202 is sufficiently heated to its stable state, the entire circuit is excited by the external power source. When the power plug 2 12 is removed from the power outlet 208, the movable contact arm 214 will be uncoupled from the static contact arm 216 and returned to its normal open position, whereby the PTC heater 202 is only rechargeable by replacing the external power source. The battery is energized and thus heated or insulated. Fig. 13 is a block diagram showing the charger 1C which can be used in the embodiment shown in Fig. 5 described above. This can be used as a protector for rechargeable Ni-Cd or Ni-MH batteries. This 1C can be sold by Ricoh Corporation of the United States and its R5440N2xxA series, which can detect overvoltage and block a charging current. It includes overvoltage detectors VD1, VD3, low voltage detectors VD2, VD4, an oscillator circuit, a reference unit, a delay circuit, and a logic circuit. Figure 6 shows a circuit diagram of an electrical appliance, generally designated 300, in accordance with a third embodiment of the present invention. When the appliance 300 is connected to an external power source (not shown), current flows through the coil 304 of a relay 306, thus attracting one of the poles D6 of the relay 306 to be connected to the T61 position, thus interrupting the PTC heater 302 and the appliance 300.

At the same time, the timer 1C 3 10 triggers a transistor TR62 so that current flows through a red light emitting diode (LED) L62 and a transistor TR62, and thus the LED L62 becomes bright. When the timer 1C 3 10 counts down to zero, the timer 1C 310 resets the transistor TR62 to the off state. When the transistor TR62 is off, no current flows through the LED L62 and the transistor TR62. The current flows through transistor TR61 and thereby illuminates a green LED L61, indicating that PTC heater 302 has achieved its relatively stable and low current state and is therefore ready for use. When the electrical appliance 300 is disconnected from the external power source, no current will flow through the coil 304, and thus the pole portion D6 will return to its normal closed (NC) position to connect with T62. The PTC heater 302 is then connected to and energized by the battery 308 and thus insulated or heated. The integrated circuit which can be used as the timer 1C 310 can be sold by Unisonic Technology Co., Ltd. of Taiwan, and its series UTC NE555, one of which is shown in the block diagram of Fig. 12. When operating in an unstable mode, the frequency and duty cycle of this 1C is controlled by two external resistors and a capacitor of R1, R2 and C1 of Fig. 6.

The circuit diagram of an electrical appliance (8). This electric appliance 400 differs from the above-described third embodiment mainly in that a plurality of rechargeable batteries 406 are provided in the electric appliance 400. A charger integrated circuit (IC) 408 and a resettable device 410 are also provided to protect the rechargeable battery 406 from overcharging. When the electrical appliance 400 is electrically coupled to an external power source (not shown), the rechargeable battery 406 is recharged under the control of the charge 1C 408 and the resettable device 410. Figure 8 is a circuit diagram showing an electrical appliance generally designated 500 in accordance with a fifth embodiment of the present invention.

When the circuit current is high, an electric crystal TR82 is triggered to conduct, so that current will flow through a red LED L82 and a transistor TR82, thus illuminating the red LED L82. When the PTC heater 506 is sufficiently heated to a steady state, the current becomes low. When the transistor TR83 senses that the current flowing through the resistor R9 is reduced below a predetermined reference level, the transistor TR82 is loaded. The value of the predetermined reference level is determined by the power value of the PTC heater 506 and the input voltage value of the external power source. The values of resistors R8 and R9 may have to be changed in response to changes in the power value of PTC heater 506 and the input voltage value of the external power source. When the transistor TR82 is worn, no current flows through the red LED L82 and the transistor TR82.
